If inhaled: If inhaled, remove to fresh air. Get medical attention if symptoms occur.
In case of skin contact: Thaw frosted parts with lukewarm water. Do not rub affected area. Get medical attention immediately.
In case of eye contact: Get medical attention immediately.
If swallowed: Ingestion is not considered a potential route of exposure.
Most important symptoms and effects, both acute and delayed
Symptoms:
Inhalation of high concentration may cause
Cardiac sensitisation
Anaesthetic effects
Light-headedness
Dizziness
confusion
Lack of coordination
Drowsiness
Unconsciousness
Risks: Contact with liquid or refrigerated gas can cause cold burns and frostbite.
Indication of any immediate medical attention and special treatment needed
Treatment: Treat symptomatically and supportively.
Fire-fighting measures
Extinguishing media
Suitable extinguishing media: Not applicable
Will not burn
Unsuitable extinguishing me-dia:
Not applicable
Will not burn
Special hazards arising from the substance or mixture
Specific hazards during fire-fighting:
Exposure to combustion products may be a hazard to health.
If the temperature rises there is danger of the vessels bursting due to the high vapor pressure.
Hazardous combustion products:
Hydrogen fluoride
carbonyl fluoride
Carbon oxides
Advice for firefighters
Special protective equipment for firefighters:
Wear self-contained breathing apparatus for firefighting if nec-essary. Use personal protective equipment.
Specific extinguishing methods:
Use extinguishing measures that are appropriate to local cir-cumstances and the surrounding environment.
Fight fire remotely due to the risk of explosion.
Use water spray to cool unopened containers.
Remove undamaged containers from fire area if it is safe to do so.
Evacuate area.
Accidental release measures
Personal precautions, protective equipment and emergency procedures
Personal precautions:
Evacuate personnel to safe areas.
Avoid skin contact with leaking liquid (danger of frostbite).
Ventilate the area.
Follow safe handling advice and personal protective equipment recommendations.
Environmental precautions
Environmental precautions:
Prevent further leakage or spillage if safe to do so.
Retain and dispose of contaminated wash water.
Methods and material for containment and cleaning up
Methods for cleaning up:
Ventilate the area.
Local or national regulations may apply to releases and dis-posal of this material, as well as those materials and items employed in the cleanup of releases. You will need to determine which regulations are applicable.
Section "disposal Considerations" provides information regarding certain local or national requirements.
Handling and storage
Precautions for safe handling
Technical measures: Use equipment rated for cylinder pressure. Use a backflow preventative device in piping. Close valve after each use and when empty.
Local/Total ventilation: Use only with adequate ventilation.
Advice on safe handling: Handle in accordance with good industrial hygiene and safety practice, based on the results of the workplace exposure assessment
Wear cold insulating gloves/ face shield/ eye protection.
Prevent backflow into the gas tank.
Open the valves slowly to prevent pressure surges.
Close valve after each use and when empty. Do NOT change or force fit connections.
Prevent the intrusion of water into the gas tank.
Keep away from heat and sources of ignition.
Take precautionary measures against static discharges.
Take care to prevent spills, waste and minimize release to the environment.
Avoid breathing gas.
Valve protection caps and valve outlet threaded plugs must remain in place unless container is secured with valve outlet piped to use point.
Use a check valve or trap in the discharge line to prevent haz-ardous back flow into the cylinder.
Use a pressure reducing regulator when connecting cylinder to lower pressure (<3000 psig) piping or systems.
Never attempt to lift cylinder by its cap.
Do not drag, slide or roll cylinders.
Use a suitable hand truck for cylinder movement.
Hygiene measures: Ensure that eye flushing systems and safety showers are lo-cated close to the working place. When using do not eat, drink or smoke. Wash contaminated clothing before re-use.
Conditions for safe storage, including any incompatibilities
Requirements for storage ar-eas and containers:
Cylinders should be stored upright and firmly secured to pre-vent falling or being knocked over. Separate full containers from empty containers. Do not store near combustible materi-als. Avoid area where salt or other corrosive materials are pre-sent. Keep in properly labelled containers. Keep in a cool, well-ventilated place. Keep away from direct sunlight. Store in accordance with the particular national regulations.
Advice on common storage:
Do not store with the following product types:
Self-reactive substances and mixtures
Organic peroxides
Oxidizing agents
Flammable liquids
Flammable solids
Pyrophoric liquids
Pyrophoric solids
Self-heating substances and mixtures
Substances and mixtures, which in contact with water, emit flammable gases
Explosives
Acutely toxic substances and mixtures
Substances and mixtures with chronic toxicity
Storage period: > 10 yr
Recommended storage tem-perature:< 52 °C
Further information on storage stability: The product has an indefinite shelf life when stored properly.

Exposure controls / personal protection
Control parameters: Contains no substances with occupational exposure limit values.
Exposure controls
Engineering measures
Ensure adequate ventilation, especially in confined areas.
Minimize workplace exposure concentrations.
Personal protective equipment
Eye protection: Wear the following personal protective equipment:
Chemical resistant goggles must be worn.
Face-shield
Hand protection
Material: Heat resistant gloves
Remarks:
Choose gloves to protect hands against chemicals depending on the concentration and quantity of the hazardous sub-stance and specific to place of work. For special applications, we recommend clarifying the resistance to chemicals of the aforementioned protective gloves with the glove manufac-turer. Wash hands before breaks and at the end of workday. Breakthrough time is not determined for the product. Change gloves often!
Skin and body protection: Skin should be washed after contact.
Respiratory protection: Use respiratory protection unless adequate local exhaust ventilation is provided or exposure assessment demonstrates that exposures are within recommended exposure guidelines.
Filter type :Organic gas and low boiling vapour type (AX)
Protective measures: Wear cold insulating gloves/ face shield/ eye protection.
Stability and reactivity
Reactivity: Not classified as a reactivity hazard.
Chemical stability: Stable if used as directed. Follow precautionary advice and avoid incompatible materials and conditions.
Possibility of hazardous reactions:
Hazardous reactions: Can react with strong oxidizing agents.
Conditions to avoid

Disposal considerations
Waste treatment methods
Product:
Dispose of in accordance with local regulations.
According to the European Waste Catalogue, Waste Codes are not product specific, but application specific.
